Amazon Will Be Drier Because of Global Warming, But Won't Turn to Savannah

Under some global warming scenarios, Amazonia becomes so significantly drier that parts of the tropical forest begin turning into savannah. The good news is that that probably won't be the case, at least according to new research published in the Proceedings of the National Academy of Sciences. Previous rainfall projections underestimated the amount of rainfall the region will still have:Seasonal Forests Could Replace Rainforest
According to the new research, "The rainfall regime in eastern Amazonia is likely to shift over the 21st century in a direction that favors more seasonal forests rather than savannah." Though rainfall is likely to diminish it would still be enough to maintain forests; they just would have pronounced wet and dry seasons.

The scientists point out that these seasonal forests would be more drought resistant, but also more vulnerable to fire, than the rainforest that currently covers the region.
